THE HEIRESS' Jessica Chastain announced on her Facebook page on Thursday that she will not be performing on Broadway on January 10th, 13th and 27th to support her film Zero Dark Thirty at the Critic's Choice, Golden Globes and SAG Awards. Her understudy Mairin Lee will be playing the role of 'Catherine' on those dates.

"I hope everyone is having a beautiful holiday surrounded by their loved ones. My family flew into NY so we could all be together. It's been wonderful to have them here. I feel very grateful to have so much love in my life, and yes, that includes all of you. I wanted to give you all a heads up regarding the schedule for The Heiress," she wrote. "If you've bought tickets for those dates, the theatre will exchange them for you. Sorry if this inconveniences anyone."

The new Broadway production of the Tony Award winning play The Heiress opened on November 1 and plays a strictly limited run through February 10, 2013.
